A great example of Brutalist architecture, it divides opinion sharply [OC]

I actually think this is an above-average implementation of brutalist architecture. It is at least visually interesting.

Would this really be considered brutalist? I mean, there's not enough undecorated walls of concrete

It actually has protected status in part because it is an example of brutalism. To quote its listing:
"Architectural innovation: the building displays an unusual blend of New Brutalist architecture (influenced by late Le Corbusier) that is mellowed by an inspired application of upturned curves to the main elevations, sweeping car park ramps and the curved ends of the former taxi rank."
Concrete wasn't necessarily a defining feature of brutalist architecture, it was just the thing that was really cheap and available in abundance when Europe was attempting to rebuild itself in the wake of WWII. Since brutalism does avoid the decoration or adornment of materials, in practice this resulted in a lot of visible concrete, but it's not like designers were going "let's use concrete only because it's the fashion"
- "let's use concrete only because it's the fashion"
  This is a paradoxical sentence in this context. Raw material was used because it was practical and functional, but at the same time it was fashionable too.
  It's precisely what fashion is, a trend in design in a certain art school. However the lack of an aesthetic ideology does make it anti-fashion too.
  One could say that the embellishments that mellow out the raw/harshness of the brutalist style is antithetical to it, though. It's think that Corbusier would take offense with his name associated with this.
it has the monumental size and far too large unwelcoming open spaces but yeah it could be uglier

Reminds me a bit of a tollbooth.

In typical brutalist fashion, there appears to be very little natural lighting on the upper floors.

It annoys me that they didn't build this right by the train station. Instead it's likely literally at the other end of town.

When reality itself is brutal AF, architecture horning in is a tiresome and formerly-clever exercise. 🤷🏼‍♂️

I'm fairly sure you're just making a joke about the name here, but brutalist architecture was actually a pretty genuine attempt to improve the circumstances of the public. The thinking was basically to put function over form and then embrace the raw appearance of materials and make it a feature. It didn't always succeed at this, but th ethinking was pretty good
- Brutalist architecture follows function through form about as well as modern big box warehouses. Slather a bunch of concrete or other rock together, make sure it’s dimly lit with recessed or tiny windows, then make sure none of these windows open to let in fresh air.
  Remember how prior to 1970 you had these cool grocery stores with curved rooflines and all glass fronts? Now you have square boxes with flat rooflines that leak, stained drop ceilings, and garish fluorescent lighting. Same concept.
- Yes, it was a half-baked joke at best, but at least I didn't exhale?
brutalism was actually a monumentally optimistic vision of the future
- Thank you for the summary of the preceding comment, citizen. Your veracity has been noted. Carry on.
